Essential concepts

There is beauty at all levels of sophistication and all levels of abstraction.

- David A. Blackwell

If life were really fair, algebra would actually come in handy

- Amstel Light commercial

On programming and deadlinesObserve that for the programmer, as the chef, the urgency of the patron may govern the scheduled completion of task, but it cannot govern the actual completion. An omelet, promised in two minutes, may appear to be progressing nicely. But when it has not set in two minutes, the customer has two choices -- wait or eat it raw. Software customers have the same choices..

- Fred Brooks

We don’t have time to stop for gas -- we’re already late.- Old software project planning proverb via Mike Cleron

I love deadlines. I like the whooshing sound they make as they fly by.

- Douglas Adams

Why is programming fun?What delights may its practitioner expect as a reward?First is the sheer joy of making things

Second is the pleasure of making things that are useful Third is the fascination of fashioning complex puzzle-like objects of interlocking moving parts

Fourth is the joy of always learningFinally, there is the delight of working in such a tractable medium. The programmer, like the poet, works only slightly removed from pure thought-stuff.

On education

The college you attend does not determine the scope and possibility of your life’s achievements. It will have some influence, no doubt. What is more important is the encouragement that we, as parents and friends, offer these prospective students as they explore their own educational trail. In the end, the experiences they encounter and the depth of character they build along the way will mean far more than the name of the institution on their diploma.

- John Hennesy

Education is not filling a bucket but lighting a fire. - William Yeats

On educationAn education isn’t how much you have committed to memory, or even how much you know. It’s being able to differentiate between what you know and what you don’t.

- Anatole France

The best way to have a good idea is to have lots of ideas.

- Linus Pauling

If there is no struggle, there is no progress- Frederick Douglass

The ability to quote is a serviceable substitute for wit. - W. Somerset Maugham

Laws governing computer science Moore’s Law (1965)

The number of transistors per area on a chip double every 18 months

Density of transistors => more functionality and speed

How about multiple computers? Amdahl’s Law (1967)

Given: fraction (s) of work to be done is serial (i.e. isn’t parallelizable)

Maximum speedup with infinite number of processors is 1/s
